Global Warming: What needs to be done?

Well, last time I checked, Methane was a Greenhouse Gas. Methane traps heat 20 times more effectively than Co2.

Correct.

70% of the Methane in the atmosphere is produced by plants, wetlands, animals and of course- the Ocean.

Roughly correct.

Huh, I guess the rise in Greenhouse gases ISN'T caused by humans ONLY like you state.

[/ QUOTE ]

Not correct. The increase in methane gas over the last century or so can by largely accounted for by increase in industrial activity by humans.

I have a feeling that much like the 'shortage' of proven oil reserves, the same miracle will occur when we need much more fissionable material.

In practise there is enough for the forseeable futue, because it's contained in trace amounts in sea-water. The economics of extraction are a bit dubious. Thorium and plutonium reactors are probably also doable. Obviously I can't say much about the presence of unknown unranium resources [img]/images/graemlins/grin.gif[/img] but my point is that running out of land is not a major issue, and nuclear power as it is used today is not inexhausible.

Wouldn't it be nice if fusion energy became the national goal?

Fusion power is a sweet con job by physicists to get governments to part with insane sums of money for high-energy plasma-physics research. We could generate power from fusion - some people think it's doable with current tech, just scale up what we have - but the economics make no sense. Fusion reactors are expensive.
